Hi guys, so I am putting the final touches on the lq4 I have been putting together to swap into my truck and am wondering if I need to upgrade injectors and if so what size would you recommend? motor is a 2001 370ci lq4, stock crank with forged rods and pistons, custom cam from Martin Smallwood (can get specs if needed), untouched 243 heads, and factory truck intake. I am thinking it will be around 400fwhp and probably around that if not more torque judging from setups I've seen similar to mine so I am assuming I will need to upgrade the injectors. Thanks

What intake and wiring harness?

using the factory truck intake. I am going to be re-pinning the factory 5.7 vortec harness to work with the lq4, so using the factory lq4 injector harness.

Id look for some flex fuel injectors or 8.1l. Those should set you up and not be so pricey plus youd have the factory info/offsets to plug right in.
